Stardock will be closed for the week starting on Monday, June 29th and we will be returning on Monday, July 6th. We will be monitoring support tickets and forums during this time but expect delays in responses during this time.
What's happening when you try to activate? Can you send your account details to [email protected] ( not a good idea to post them 
)
